DAPI

DAPI (4',6-diamidino-2-phenylindole) is a fluorescent dye used by scientists to visualize DNA in cells. When added to a cell sample, DAPI binds specifically to DNA within the cell nucleus. Under UV light, the dye emits a bright blue fluorescence, allowing researchers to see and study the genetic material. This makes DAPI a valuable tool in biology for examining cell structure, counting cells, and analyzing genetic material in research and diagnostics. It’s safe to use under controlled conditions and provides clear visualization of DNA inside the cells.
